Clock operation

Write timing

When writing to the device, the data is shifted into the M41T62's I2C interface on the rising

edge of the SCL signal. As shown in Figure 20, on the 8th clock cycle, the data is

transferred from the I2C block into whichever register is being pointed to by the address

pointer (not shown).

Writes to the clock registers (addresses 0-7)

Data written to the clock registers (addresses 0-7) is held in the buffer registers until the

address pointer increments to 8, or an I2C stop condition occurs, at which time the data in

the buffer/registers is simultaneously copied into the counters, and then the clock is re-

started.
